Bethany Reservoir State Recreation Area

Bethany Reservoir is a recreation area covering about 609 acres in the northern San Joaquin Valley with a large artificial lake surrounded by open grassland and waterside areas. The site includes parking, picnic areas with grills, restrooms, and several trails for different types of visitors.

The area was established in 1974 by the California Department of Parks and Recreation to store water for the California Aqueduct system. From the start it served both water management and recreational purposes for the region.

The reservoir serves as a gathering place where anglers, families, and water sports enthusiasts spend time together outdoors. Local visitors use the open spaces and waterfront for leisure activities and celebrations throughout the seasons.

The area is open year-round, though conditions vary by season and weather patterns. Bring water and sun protection, and stick to marked paths, especially during hotter months when temperatures can be intense.

The waters here are well-suited for windsurfing due to wind patterns that make conditions favorable for the sport. This quality has drawn water sports enthusiasts who come specifically for the wind and wave conditions the reservoir offers.
